What are you favorite show openings/intros (the beginning song that introduces a show) and closings/outros (the end song at the, uh... end, obviously)? They don't necessarily need to be anime intros and outros, but I have a suspicion that those are what most people are going to list.

Anyways, my favorite show openings and closings are the ones from Paranoia Agent or the first opening and closing of FMA.
